Mostly it's about Go 1.22+ syntax with ranging over integers, but it also
prefers ranging over slices where possible (it makes code a little better to
read).
Notice that we have a number of dangerous loops where slices are mutated
during loop execution, many of these can't be converted since we need proper
length evalutation at every iteration.

the server starts sending messages.

BlockFilter has PrinaryIndex of int type while block.Block structure
itself has PrimaryIndex of byte. It's needed to prevent changing
filters field type and all associated subscriptions logic on
server side.

New event is to notify the user about header's content by the moment
when block is stored (which happens after block's processing). This is
needed for proper Waiter work.

The reader is about to exit and it will close legacy c.Notifications, but it
will leave subscription channels at the same time. This is wrong since these
channels will no longer receive any new events, game over.

Regular Client doesn't care much about connections, because HTTP client's Do
method can reuse old ones or create additional ones on the fly. So one request
can fail and the next one easily succeed. WSClient is different, it works via
a single connection and if it breaks, it breaks forever for this
client. Callers will get some error on every request afterwards and it'd be
nice for this error to be the same so that API users could detect
disconnection this way too.

It should be noted that the subscriber's channel is being removed from the
list of receivers and closed, but it is still *in the list of subscribers*
and no unsubscription is performed by WSClient. Which means that RPC server
keeps sending notifications to WSClient and WSClient keeps dropping them
(because there's no receiver for this subscription and it's OK, WSClient
can handle this and this behaviour is documented). However, it's still the
caller's duty to call Unsubscribe() method for this subscription.
